on 19/12/2017Disclaimer! I am learning NSX-T, part of my learning is to deploy in my lab - if I contradict the official docs then go with the docs!
Lab Environment
This NSX-T lab environment is built as a nested lab on my physical hosts. There are four physical ESXi hosts, onto which I will deploy three ESXi VMs, a vCenter Server Appliance, NSX Manager, an NSX Controller cluster, and two NSX Edge Nodes.

on 31/1/2017Equal Cost Multipathing (ECMP), for the vSphere admin, is ability to create routes with an equal cost, which allows multiple paths to the same network to be created and traffic can be distributed over those paths. This is good for a couple of reasons - firstly is availability. If we were to lose a host, and an NSX Edge, the route will time out quicker than NSX Edge High Availability - thus providing higher availability for our network traffic. Then second reason is throughput - each NSX Edge is capable of ~10Gbps throughput, but with ECMP we can have multiple NSX Edges (up to 8) providing 10Gbps each - that’s a significant performance boost.
